Versuchsvorschrift

A solution of 810 mg (3.0 mmol) of methyl 3-amino-2-benzoylamino-benzoate 9y in 15 ml acetic acid was heated to 125° C. for 1.5 h. The reaction was cooled and poured into ice/water. The aqueous layer was made basic with NaHCO3 and extracted with CH2Cl2. The organic solution was dried over Na2SO4 and evaporated to give 540 mg (71%) of methyl 2-phenyl-1H-benzo[d]imidazole-7-carboxylate, 9z. MS m/z (M+H+) 253.2
